Newbie question : Xerces (C++) How do I create the <?xml version="1.0" encoding="UTF-8" ?> header

[mel-tey chamon!]

I have created a XML Writer program, and everything works, but I need to
revice my code and add this "version and encoding" header for completeness
and correctness... I am completely stuck!

I have done this so far:

DOM_Element root = xmlDoc.getRootElement();
root.setAttributes ("xmlns","etc.etc.");

Do I have to previous root called "?" - but this doesn't make much sense as
the tag begins "<?xml" and ends "?>"

From scouring the web, I believe that I coding with a legacy version of
xerces-c. (hence DOM_Element)
I cannot change or update the library

Please can I have a snippet of code?

Thanks a lot!

This is called the XML declaration. It's not an element. There should
be an attribute on the document class which says whether to write the
XML declaration, though.
